Comparitive Evaluation of Antimicrobial Efficacy of Ocimum Sanctum, Tridax Procumbens and Mango Kernel Extracts With Sodium Hypochlorite and Chlorhexidine as Rootcanal Irrigants - An Invitro Study

Enterococcus faecalis and Candida albicans have a major role in the etiology of retreatment cases. It
is frequently found in high percentage of root canal failures and can be seen as single organism or as a
major component of the mixed flora.Various investigations have demonstrated that thorough and complete
debridement of rootcanal system is impossible with mechanical driven or hand instrumentation to eliminate
the microorganisms and their byproducts. Hence, endodontic preparation should be supported by irrigants
for enhanced disinfection. The use of conventional irrigants especially sodium hypochlorite (NaOCl) is
highly efficient in eliminating E.faecalis biofilm. But its major disadvantage is its tissue toxicity and in
addition it doesnot remove all of the smear layer, for which reason plant products that are consumed orally
for varied medicinal purpose are assayed for their antibiotic properties.
The present study resulted in a conclusion that combination of 2% chlorhexidine and mango kernel shows
superior antimicrobial efficacy to that of 5.25% NaOCl,& 2 % Chlorhexidine against strains of E.faecalis &
C.albicans and also shows that the new bio irrigant has good shelf life and rapid onset of action.
